The theory associated
pollution, soil
pollution, soil conditions, land mass, toxins or contaminants. As a result of adding or dropping things. Into the ground than the standard The impact on the health of the organism and the environment
matter that pollute the soil
first. Pollutant living like parasites, bacteria, viruses, which these organisms cause disease to humans, Szeged and creatures in the soil
2. Ml chemicals such as inorganic species. If there is too much salt can cause. Organic substances or pesticides. Which is transmitted to the food chain. And will add more volume rank consumer
3. Ml, such as radioactive substances from the power plant, New Jersey Mikkeli. And atomic reactors are radioactive radiation from gamma rays, beta rays, which have an exciting radiation, these residues in the soil. Will affect the life of some mutations
cause soil pollution,
soil loss by nature, for example the acid soil salinity, soil, peat or soil organic matter. Soil containing radioactive materials And soil contaminated with heavy metals or
dust because of human actions
- the use of chemical fertilizers in science. To increase agricultural productivity can be divided into two main groups of fertilizers containing elemental mainstay plants include nitrogen (N), phosphorus (P) and potassium Poe (K) when used for a long time to make the acid soil. Have high acidity
- the use of chemical pesticides (pesticides) soil is a collection of chemicals that are byproducts of chlorine, organic compounds, such as long. (organochlorine), etc., and inorganic substances in the use of toxic elements such as arsenic, copper, mercury, etc. are the main components
- allowing waste water from the production process. The waste water from leaching through the various chemicals in industries such as PCBs (PCB) used in the manufacture of paint and plastics additives H. Brooks (HCB), used in the manufacture of synthetic rubber
- the soil. the dumped waste In particular, the dumping hazardous waste materials which are difficult to decompose. To accumulate In soil and cause soil pollution
- radioactive leakage. Experimental or industrial or from atomic reactors. Radioactive materials are Absorbed into the leaves and flowers of plants. Through the food chain until the man
- almost all mining will affect the environment. Whether the soil or water resources to achieve. Contaminate and pollute the air
pollution control and land
- use legal measures to control the use of land resources to control land use right
- the protection of technological measures. Soil pollution control, waste disposal and other sources, as well as the right to control the use of chemicals. And should be subject to investigation and surveillance of soil quality by consistently incorporating educational knowledge and understanding about pollution prevention and clay
soil. Toxic
soil toxicity Refers to a condition that can not be made up of waste and toxins. Which may be organic
or inorganic substances. By adsorption on soil particles. The problem that constantly followed. The problem is that this type of The amount and activity of soil microorganisms have been affected directly and indirectly. The process of making changes to microbial degradation. Plants grown in soil that is toxic to a quality of output. The plant will have an accumulation of toxins in various parts of the plant life on other plants, this will consume the toxic range. Broadcast to those creatures. As a result, the health problems caused by
the toxic soil can occur spontaneously. Such geological changes causing the formation of rocks and minerals. Which can cause toxicity. The creatures But the amount of toxins in the soil, it will be up to other environments, such as acidic - pH, temperature in some cases, the toxic soil. Due to the soil in areas with radioactive ore. Hence, the soil in the area is toxic
to human activities that cause soil toxicity can be divided into two groups. Agriculture and
industry
- toxic soil in the agricultural sector. The fertilizer into the soil to support agriculture more productive. This will cause the precipitation of toxins. The accumulation of toxins Changes in the condition of the soil, making the soil more acidic. Or physical properties of the soil deteriorates. Make a greater microbial activity. Including the use of pesticides as well as organic and inorganic substances are toxic to destroy life on earth. Or microorganisms in soil The negative effect of the plants that grow in the area. However, depending on the stability of the soil. This is based on the half-life (Half life period) of the pesticide. The half-life means that figures to estimate that about half of life over time. The amount of material that will be reduced to half the amount of substrate.
